He may be the king of Carpool Karaoke, but James Corden says he won't be singing as host of Sunday's Grammy Awards.

"There are a lot of brilliant singers there," he says, "and no one needs to hear me disrupt such beautiful vocals."

Corden also says he isn't trying to be the next LL Cool J, Grammy host for the past five years.

"I'm more like, not Ladies Love Cool James," he says. "I'm like Ladies Put Up With That Guy James. It's not as catchy."

Corden talked about his Grammy gig after rolling out the ceremonial red carpet Thursday with recording academy president Neil Portnow and show producer Ken Ehrlich at Staples Center in Los Angeles.

Though Corden is on TV every night as host and writer of "The Late Late Show" on CBS, he said taking on the Grammys is something else entirely.

"My show is basically on in the middle of the night where people only really catch it if they wake up and happen to realize they've left the television on," he said. "This is very different. This is the Grammy Awards, and there are quite a few more people watching it. So, you know, we're really going to try our best to not ruin the whole thing. That's really our jumping off point: Don't ruin it."
